LAMP FOR LIGHTING HOUSES AND OTHER kPLACES.

Specification of Letters Patent N0. 246, dated June 80, 1837.

T0 all whom t may concern Be it known that I, SAMUEL RUST, of the cityof New York, co-unty and State of N ew York, have invented a new anduseful Improvement in Lamps for Lighting Houses and other Places, andthat the following is a full and correct description of said improvementas invented or improved `by me.

The nature of my invention or improvement in the above said lamp,consists of a cast metallic stopple used independent lof a screw withthe tubetor socket to receive the wick Vinserted or made in it, whichstopple is to be used in place of the usual screw andV cork stoppleheretofore used in said lamp. The inside of the neck of glass or otherlamps in which this stop-ple is used, must be ground or made true, inthe manner of stoppered bottles, which is done with a very small expenseand the stopple also turned or ground to tight; or, in vthat part of thestopple whlch enters the lamp, Va groove or recess is to be made toreceive an elastic substance, such as thread cotton or other mate-rial;either of which modes does away with the complication and perplexity ofthe screw, and also Vfrom the swelling, contracting, and leaking of thecork; which improved stopple is particularly calculated for glass lamps.

This cast metallic stopple is made hollow and thin with a ange,shoulder, or projection around it for the purpose of covering over theedge of the glass `or metal top or neck, serving as a stop to prevent itfrom'pressing too hard or far intothe lamp; this stopple is turned orotherwise made true, and is calculated forA the round tube or otherlamps; or, for S. Rusts patent rollei1 lamp, for which he obtainedLetters Patent of the United States, dated the sixteenth day ofDecember, 1835.

For further illustration the annexed drawings with the explanations arereferred to as making a part of this specification. A, Figs. l and 2, isthe metallic 'stopple in the lamp. B, Fig. 3 is the metallic stopplerep-r resented out of the lamp.

My invention or improvement andfwhat I claim in this patent .does notconsist in a roller or ina flange, or in a tube, but it cons sists of- YA cast metallic Stopple used independent of a screw, or of a cork,ground, or otherwise truly fit-ted into glassY or other lamps, andinserted the same as a cork, as aforesaid and as above'described, or inany other way ormanner that is essentially' the same and for which Irequest Letters Patent.
